It’s not easy to eat right all the time and even if you are you may not know that consuming fruit, for instance, with protein will inhibit your bodies ability to absorb the nutrients you are ingesting.

Taking certain supplements will help to insure that you are getting the nutrients you need everyday.

Bioavailability and absorption are two important factors when it comes to sufficient intake of micronutrients. For example, oxalates are a chemical found in tea. While herbal teas are good for you, this chemical can limit the bioavailability of several nutrients, like iron and calcium. Tea has become as much a staple in many diets as coffee or water – meaning your body may not be benefiting from your “perfect” diet.

Another common example is consuming milk with a meal containing eggs – it is highly unlikely you will absorb much of the calcium in the milk. Iron, found in eggs, binds calcium in the intestines, limiting absorption. Ideally, these two micronutrients should be consumed three hours apart, but do you really have time for that much planning and fretting?

Supplements, however, do not replace healthy eating and lifestyle choices.

Don’t let these feelings get in the way of your fitness goals. Instead, get your iron levels checked. Low-iron or iron deficiency anemia can lead to a host of symptoms including: tiredness, low-motivation and poor circulation.

First realize that fats are a necessary part of any diet. We need fats to make hormones, build and repair tissues, and for energy. Gram per gram, fat provides about more than twice the energy of carbohydrates (9 calories per gram vs 4 calories per gram for carbs). Fats also help us absorb certain vitamins and satiates our appetite more than carbs or protein.

But there really are good fats and bad fats and the Cliff notes version of this column is this — if a fat is solid or semi-solid at room temperature, you should avoid it.

Most dietary fats fall in to three categories: Saturated fats, polyunsaturated fats, and mono unsaturated fats.
